REGISTERING DEVICE FOR PRINTING-FEE SSES.

Specification of Letters Patent.

Patented June 16, 1908.

Application filed February 17, 1908. Serial No. 416,212.

To all whom it may concern:

Be it known that I, EUGENE L. BooAson,

a citizen of the United States, residing at.

2279 North Francisco avenue, in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Registering Devices for Printing-Presses, of which the following is a specification.

My invention relates to registering devices for printing presses and particularly to reg istering devices for engravers hand presses.

The object of my invention is to provide a device particularly adapted for use upon engravers hand presses, for perfectly registering the paper with the plate in polychrome printing, in order that each color shall be properly applied or positioned with relation to the others.

A further object of my invention is to provide a device as mentioned which shall perfectly register the paper with the plate no matter what the position of the plate on the bed of the press may be, and irrespective of any movement of the plate upon the bed between impressions.

Further objects of my invention are to provide a device as mentioned which may be readily and quickly adjusted, which will remain in adjusted position without change under all ordinaryconditions, and one which. shall not readily get out of order.

Other objects will appear hereinafter.

'With these objects in view my invention consists generally in a block like member adapted to rest upon the bed of a press, means on said block for positioning a plate with relation thereto, and a plurality of fingers extending above said member for registering the paper with the plate, one of said fingers being longitudinally adjustable thereon and the remaining fingers transversely adjustable.

My invention also includes an extension device adapted for use in conjunction with plates of large size, and. comprising a block like member having a transversely adjustable finger, said device being adapted to be arranged in alinement with the main registering device.

My invention further consists in various details of construction and arrangements of parts all as will be hereinafter fully described and particularly pointed out in the claims.

My invention will be more readily under stood by reference to the accompanying drawings forming a part of this specification and in which,

Figure 1 is a plan view of a registering device embodying my invention in its preferred form, a portion of the device being broken away to better illustrate its structure, Fig. 2 is a vertical longitudinal section on the line ac-a: of Fig. 1, Fig. 3 is a transverse section on.the line y-y of Fig. 1 upon an enlarged .scale, Fig. 4 is a detail of the plate positioning device, Fig. 5 is a diagrammatic plan view illustrating the device in operative position upon the bed of a press, and Fig. 6 is a similar view illustrating the extension device in use.

Referring to the drawings the registering device comprises an elongated rectangular block 1 having a plurality of transverse recesses 2 and a longitudinal recess 3 closed at the bottom by a plate 4 and at the top by a plate 5. The block 1 is preferably formed of wood although any suitable material may be employed, and the recesses 2 and 3 extend through said block from top to bottom. The plates 4 and 5 are co-extensive with the lower and upper faces of the block and close the recesses 2 and 3 except for the slots 6 and 7 in the plate 5 arranged above and parallel with the center or axis of the recesses 2 and 3 respectively. The block is preferably perfectly true and square especially as regards the front edge 8 and the upper and lower surfaces defined by the plates 4 and 5 and the block is preferably just the height of the type or plate to be used. Adjustably fixed to the edge 8 and near one end thereof is a plate positioning device. This comprises an angular member consisting of an arm 9 longitudinally slidable on the edge or face 8 and an arm 10 formed at right angles thereto. The arm 9 is provided with a longitudinal slot 11 and a thumb screw 12 extending through said slot into the block 1 adjustably secures the device to the block. In using the device it rests upon the bed of the press and the plate is shoved up into the angle formed by the face 8 and arm 10.

Extending longitudinally through each of the recesses 2 and the recess 3 is a screw 14 swiveled in a plate 15 secured to the rear face 16 of the block ,1 and inclosing the end of the recesses. The opposite end of the screw is somewhat reduced as at 17 and has bearings 18 in a block 19 fixed in the end of its respective recess. 20 indicates a block threaded upon the screw 14 and having a finger or guide 21 formed thereon and extending through the slots 6 or 7 as the case may be. Each finger comprises. a vertical portion 22 which extends through the slot forming a stop or guide 23 for the paper, and a horizontal portion or tongue 24 which overhangs the edge of the paper when inserted in printing position. By turning the screws 14in the transverse recesses, the forward or back ward position of the paper may be regulated with relation to the plate and by turning the screw in the longitudinal recess 3 its longitudinal position with regards to the plate may be adjusted.

25 are knurled heads on the several screws for turning the same.

It should be noted. that the longitudinal recess 3 is arranged adjacent to the plate positioning device, and that its respective paper registering finger is adjusted parallel therewith. Formed upon or secured. to the rear face 16 are a plurality of blocks 26 which extend a slightly greater distance from the block 1 than the knurled heads 25.

Although any number of blocks 26 may be employed I find that two are generally suflicient one being located in each end of the block 1, and I have so illustrated it in the drawings.

When the device is arranged upon the bed of the press a piece of furniture is arranged against the blocks 26 and extending from one to the other.

By having the blocks slightly longer than the screw heads they prevent the furniture from contacting the screws when in operative position upon the press.

In Figs. 5 and 6 I have illustrated the device in operative position. Referring to said figures 30 indicates the bed of a press having the corner pieces 31 for holding the furniture. 32 indicates pieces of furniture framing the bed and 33 a piece of furniture resting against the blocks 26. 34 indicates a plate resting snugly in the angle formed by the arm 10 and the face 8. To properly center the plate on the bed, pieces of furniture 35 are interposed between the piece 33 and the end of the registering device, and the furniture 32. After the device and the plate are properly positioned on the bed the screws 14 are turned until the fingers 21 are in position to properly register the paper with the plate. It is obvious that a fine ad'- justment may be had in this manner and that after adjusting the device it will remain in adjusted position indefinitely.

The device is made of a length to accommodate plates of ordinary sizes hence with very large work an extension member must be employed. This comprises a member similar to a section of the main portion of the device but being provided with but one finger 21.

36 indicates the extension member. This may rest directly against the end of the main device or may be spaced therefrom by an interposed. piece of furniture 37. To maintain the extension in alinement with the main portion it rests against the same piece of furniture 33, it being rovided with the blocks 26 similar to the b ocks 26. The extension device is so arranged that the finger 21 will engage the edge of the paper near its end as indicated in Fig. 6, 38 indicating the paper.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A registering device for printing presses comprising an elongated rectangular member having a plurality of transverse recesses and a longitudinal recess in combination with a block slidably mounted in each of said re cesses and having a finger extending above said member, a screw in each of said recesses for adjusting said blocks and means for positioning a plate with relation to said registerlng device, as and for the purpose specified.

2. A registering device for printing presses comprising an elongated rectangular blocklike member having a plurality of transverse recesses and a longitudinal recess in combination with a screw mounted in each of said recesses, a block threaded u on each of said screws, said screws and said blocks being entirely below the upper face of said member, a
